Teaspoon
Definition: A teaspoon (symbol: tsp) is a unit of volume based on an item of cutlery. The United States customary teaspoon is equal to exactly 4.928922 mL. The metric teaspoon is equal to 5 mL.
History/origin: The teaspoon was originally used as a unit of Apothecaries' measure and was equal to 1 fluid dram, ¼ of a tablespoon, or 1/8 of a fluid ounce. This definition of the teaspoon is smaller than the definitions of the teaspoon used today. This is partially due to tea being expensive in 1660s England, resulting in smaller teacups and teaspoons. Once England began importing tea from China in 1710, reducing the cost of tea, the size of teacups and teaspoons increased, and by the 1730s, became 1/3, rather than 1/4 the size of a tablespoon. This is the same size ratio in use today in both the US customary and metric teaspoons (though the actual volumes differ).
Current use: The teaspoon is widely used in cooking within certain countries, as well as for measuring pharmaceutic prescriptions. Outside of these applications, the unit is not particularly used, with measurements such as the liter or cubic meter being preferred.
Cubic inch
Definition: The cubic inch (symbol: in3) is a unit of volume in the Imperial and United States customary systems of measurement. It is the volume of a cube with measurements 1 in × 1 in × 1 in. It is equal to 16.387064 cm3 or mL.
History/origin: The cubic inch is derived from the inch, a unit of length within the imperial and US customary systems of measurement. Since the 1950s and 1960s, with the adoption of the international yard, the inch has been defined as exactly 2.54 cm.
Current use: The cubic inch and cubic foot are still used in the United States, and to some extent in the United Kingdom. However, SI (International System of Units) units of measurement are also widely used throughout these countries.
In the US, the automotive and aircraft industries in particular use the cubic inch to some extent, though the SI derived or SI accepted units of volume (liter, milliliter, and cubic meter) are also used.
In the UK, automotive model numbers are sometimes denoted in cubic inches.
